HYDROCARBON-BURNER.

To all whom 'it mayv concern:

Be it known that we, JOHN H. T. MILLS w and VIEGIL H. MILLS, citizens ofthe United States, residing at Hubbard, in the county of Hill and Stateof Texas, have invented certain new and useful Improvements inHydrocarbon-Burners, of which the follow- 4, ing is a specification.

This invention relates to oil burners and `more particularlyto thatclass ofburners in which a jet of steam or air is employed for atomizingthe fuel at the burner tip.

The object of the invention is to provide a burner of simple and durableconstruction,

capable of producing a maximum amount of heat with a minimum consumptionof fuel. A further object 1s to provide means for blowing out anyforeign deposits that may `lodge in the steam or air outlet at theburner tip, without the necessity of shutt-ing down the burner or in anymanner .interfering with the operation thereof.

A further object is to provide means where- V `by the fuel supply pipemay be quickly detached from the rear end of the burnerso as to permitthe fuel conductor to be readily `removed from the burner and cleanedwhen necessary.

l A further `object is to provide a burner having a relatively largeopening or clearance at the tip thereof to assist in ato-mizing the oil,the outer end of the oil conductor being beveled and preferably extendedslightly beyond the cap of the steam or air outlet :to prevent the oilfrom coming in contact therewith.

A further object is to provide means for centering the oil conductorwithin the casing, and means for adjusting the cap of the steam or airpipewith respect to the bevel end of the oil conductor so as to producea narrow steam outlet and also to prevent back pressure of the steam onthe liquid fuel.

Application filed November 26, 1910. Serial No. 594,317.

and the merits thereof, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a longitudinal sectional view of a hydro-carbon burnerconstructed in accordance with our invention; Fig. 2 is a side elevationof the same; Fig. 3 is a top plan view; Fig. 4 is a transverse sectionalview taken on the line 4-4 of Fig. 1; Fig. 5 is a detail perspectiveview of the pivotcd frame and locking bail detached; Fig. 6 is a detailvertical sectional view illustrating a modified form of the invention.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the' drawings by the samereference characters.

The improved oil burner forming the subject matter of the presentinvention coinprises a tubular member or casing 5 prefer'- ablycylindrical in shape, as shown, and having its inner end threaded forengagement .with 'the correspondingly threaded end of a coupling 6, thelatter being provided with lmeans for connection with a steam or airpipe, indicated at 7. Disposed within the casing 5, is an oil conductor8 having its outer end inclined or beveled at 9 and its inner endextended within and detachably secured to a sleeve 10, the exteriorwalls .of

the conductor 8 being spaced from the casing to form an intermediate airor steam chamber 11 which communicates with the supply pipe 7 andthrough which fluid from the pipe 7 is conducted to the burner tip forthe purpose of atomizing the fuel.

Threaded in one end of thecoupling 6, is a collar or bushing 12 havingits outer end provided with a flange 13 spaced from la correspondingflange formed on the coupling 6 to produce an intermediate seatinggroove 14. Disposed at the rear end of the sleeve 10, is a casting l5having its rear end closed and provided with a depression or socket 16and its front end reduced to form a nipple 17 extending within thesleeve 10, the side walls of the casting being provided with an openingto which is connected in any suitable manner a supply pipe 18, throughwhich oil is conducted to the burner tip. Seated in the groove 14, is aring 19 having secured to or formed integral therewith a transverse bar20 and provided at its opposite ends with laterally extending lugs 21 onwhich is pivotally mounted a rocking frame 22. Extending vertically fromthe upper endl ,of the frame 22, is an operating lever 23, while a lug24 depends from the bottom of the frame for connection with one end of acoil spring 25, the other end of which is secured in any suitable mannerto a pin 26 carried by the coupling 6.

Arranged at the burner tip, is a cap 27 having` oppositely disposedperforated lugs 28 to permit the passage of connecting rods `29, therear ends of said rods being formed with eyes 30 adapted to engagesuitable trunnions 31 secured to the side walls of the frame 22, saidrods being retained in position on the trunnions by cotter pins orsimilar fastening devices 32. The outer ends of the rods 29 are threadedfor engagement with clamping nuts 33, one of which bears against eachside of the adjacent lug 28. The cap 27 is provided with an opening toaccommodate the conductor 8, while the interior walls of the opening inthe cap are undercut or beveled at 34 to correspond to the inclinationor bevel 9 of the conductor, thus to permit the discharge of steam orair under pressure at the burner tip, as before stated.

It will here be noted that the outer end of the conductor 8 ispreferably of the same diameter as the inner end thereof, thus to`produce a relatively large opening or clearance at the burner tip andassist in atomizing the oil. 1t will also be noted that the beveled end9 of the conductor preferably projects slightly beyond the outer face ofthe cap 27 to prevent the oil from coming in contact therewith and alsoto prevent back pressure of the steam on the fuel. Suitable pins 35 arethreaded in the casing 5 and bear against the conductor 8 for thepurpose of centering said conductor within the casing and producing asteam or air passage of uniform width around the beveled end of the oilconductor. Thus it will be seen that by moving the operating lever 23 inthe direction of the cap 27, the latter may be spaced from the adjacentend of the casing 5 so that the steam or air from the pipe 7 may beutilized for blowing out or cleaning the burner thus to remove anyforeign particles that may find lodgment at the burner tip withoutshutting down the burner or in any manner interfering with the operationthereof.

Extending laterally from the opposite sides of the ring 19, are pins 36on which is pivotally mounted a yoke or bail 37, the latter beingprovided at its free end with a threaded opening 38 in which is mountedfor rotation a clamping screw 39. The free end of the clamping screw 39is pointed and adapted to enter the depression 16 in the casting 15 sothat by rotating the screw 39 in the bail until the pointed terminal ofsaid screw engages the recess 16, the casting 15 will be clamped withinthe sleeve 10. A suitable gasket 4() is preferably interposed vbetweenthe flange on the bushing 12 and a stop flange 39 on the sleeve 10 toprevent leakage. 1t will also be seen that by releasing the clampingscrew 39 and swinging 'the bail 37 upwardly in the direction of theVlever' 23, the casting 15 may be det-ached from the sleeve'lO and thelatter, together with the conductor 8, removed from the By having theconductor 8 A similar result may be Attention is here called to the factthat :the bail 37 is pivotally mounted on the ring 19, so that thecasting 15 and its associated ,parts may be detached from the burner andfthe conductor withdrawn from the casing without affecting the operatinglever 23 or cap 27.

A clamping nut 41 is preferably threaded Ion the clamping screw 39 so asto lock the 'screw against rotation after the latter has ,been adjustedto clamp the casting 15 in yposition on the rear end of the burner.

The cap 27 is preferably formed with a rearwardly extending sleeve 42which projects within the Huid chamber 11 and forms 'a guide for the capwhen the latter is adjusted laterally with respect to the casing eitherto effect the cleaning or blowing out ,of the burner or to regulate thewidth of 'the steam passage at the burnertip.

In F ig. 6 of the drawings, there is illustrated a modified form of theinvention in `which the inner end of the fuel conductor 8 is threaded ona gland or bushing 43, the
